To all 'whom it may concern.'

Beit known that I, OscAn A. ARNEsoN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinols, haveinvented certain new and useful Improvements in Gasolene or Vapor Lamps,of which the followinfJr is a specification.

This invention relates to improvements in the construction andarrangement of parts in lam commonly` known as gasolene or vapor ampsand is more particularly adapted to that type of lamps in which invertedmantles are used for generatin the light, al-v thou h certain featuresare a so applicable to -ot er types of such lam s. Its objects are toprovi( e a new form oflamp which will be more efficient and satisfactoryin operation than those heretofore used, which will be neat andattractive in appearance, and which will roduce an even and steady lightof Great br iancy.

attain these advanta es in my improved lamp, a preferred form o which isshown in the accompanying drawings, in which- Figure 1 is a verticalsection, arts being broken away orshown in full or convenience inillustration; Fig. 2 is a detail showing the arrangement of the doubleburners; vandFig. 3 is a sectional detail showing the burnerconstruction.

As shown in these drawings, lidesignates any suitable form of hangerwhich is 'provi( ed with one or more pipe connections 5 5 for connectionwith the main supply ipes. A valve 6 is connected with the anger 4 andwith a depending pipe 7 which carnes at its opposite end a tee 8, thistee having only one passage way through the same to allow the suppl topass through the coiled pipe 9 which lea(v s down to a valve 10, makinconnection with a horizontal pipe 11 at the ottom of the lamp. Thishorizontal pipe or tting 11 leads to a generator tube 12 runningdlametrically across the bottom of the lamp and connected at its oposite end with an upwardly extending er Aorated nipple 13 leading intoan a1r cham er 14 and.

directed toward the open mouth of a vertical ipe 15 leading upward fromsaid air chamer. The air chamber is entirel closed except for'a shortinlet pipe 16 eading out through the side of the lamp. The mixing pipe15 is connected at the top with a horizontal'iitting 16 having a passageway therethrough leading to a vertical pi 17 at about the center of thelamp, whic carries the mixed air and gas down to a forked fitting 18which in turn connects with two downwardly' projecting tubes 19 and20havin burners 21-21 at the lower ends thereo The burners 21 are threadedto screw on the ends ofthe pipes 19 and 20 and are provided with flaringoutlets 22 to direct the gas out toward the surface of the mantles 23.The mouth of the burner 22 is provided with a screen 24 which is held inposition by spinnin the end ofthe burner 21 in to engage wit the lowerouter edge of said screen. The outer surface of the lower end of theburner is provided. with a groove 25, so that a string 26 m-ay be passedaround the upper end of the mantle 23 and tied around said mantle tohold the same in position-on the burner. The frame construction of thelamp is completed by a pipe or rod 27 connecting between the lower endof the tee 8 and an upwardly projecting stem on the iitting 16, therebyserving to hold said litting and its connected parts. A rod 28 alsoconnects with a lateral projection on said fitting 16 and with the pipeor {itting 11 heretofore described.

Around the centrali disposed portions of the lam frame is a shell orcasing 29 connected y means of strips 30 and a shield plate 31 with acover portion 32 which is ccnnected by means of a thimble or sleeve 33and a set-screw 34, with the pipe 27, and servesto hold the casin inadjusted position. The casing 29 is slotted at the bottom at 35 toreceive the pi e 11 and is provided with a downwardly an outwardlyprojecting shade support 36 which is held in position by means of screws37 passing through said casin 29. This support 36 serves to hold the shae or globe 38 which may be made in any desired style. The casing 29 isprovided Wlth a hole to receive the air inlet 16, heretofore described,and with a series of holes 39 near the top to allow for the exit of theheated gases or for the inlet of air to cool the u per portion of theburner pipes, there being a so an outlet for the gas formed between theupper end of the casing 29 and the cover 32. A deflector 40 is insertedbelow the cover 32 in order to direct the gases out through the openingunderneath said cover.

T arrangement of the air mlet 1sof partlcular importance, a's the air is only allowed to ass' in througha large opening at one side o the mixin chamber, which tends to preventiiickermg of the lamp and reduce the noise of the inrushing air to aminimum. It will be supply is noted that the arrangement whereby theprevented from bein heated and \what 1s commonly termed doub egeneration is prevented, is an important feature in connection with thisimproved lamp, as it in- `27, so that a eures a steady light withoutflickering.

The arrangement ofthe casing is such that by removing the air inlet tubeand the shade holder, it ma be easily shoved up on the rod of theoperating parts of the burner are readily exposed for cleaning or insection.
